Formerly-Wasteful Bob—previously known as Wasteful Bob—was cleaning out his MS IE bookmarks when he ran across this link on the Q&A site Quora.com: “How do I cut cloud costs with AWS?”
Now that Bob was reducing his monthly AWS costs significantly by using ParkMyCloud to program EC2 instances to go off during slack periods, he didn’t really need to click the link—but he did anyway to see if there were any new and useful ideas.
What first struck Bob was how involved, complex and wordy some of the answers were. Perhaps because the respondents were mostly technical folks, Bob thought, they went into more detail then necessary. He scanned further and saw that most of the answers contained 4+ bullet points putting forth various “principals” and emphasizing “deltas,” “sizing” strategies and laborious-sounding “discount” assessments—not to mention encyclopedic details on how to leverage the full range of AWS options (Spot, RI, etc.).
For fun, Bob did a word-count on each answer:
Why, Bob wondered, did optimizing his AWS environment and reducing his AWS spending have to be so complicated? He thought of it like this: About 70% of his bill was EC2. More than half of the instances were non-production (test, Dev, QA, and staging), so they did not need to run 24×7. So the answer really boils down to finding a simple and inexpensive way to automatically program your instances to turn off when not being used.
At that instant, Bob happened to catch a few specifics from the 37-word answer—the shortest one on the page:
One of the simplest ways is to turn off unused instances! ParkMyCloud is basically a programmable on/off switch for AWS EC2 instances. Like NEST for the cloud. www.parkmycloud.com.
Formerly-Wasteful Bob was experiencing what researchers call buyer-validation. While his peers were stuck with their traditionally complicated, labor-intensive and time-consuming methods of scripting and Reserved Instance management, he felt smart for having selected ParkMyCloud. With ParkMyCloud, Bob needs to spend just a few minutes a week (if that) to reduce his AWS spending by 20% – 50%.
